ECMAScript spec abstract operations.
|
|
14
|
When different versions of the spec conflict, the default export will be the latest version of the abstract operation.
|
|
15
|
All abstract operations will also be available under an `es5`/`es2015`/`es2016`/`es2017`/`es2018`/`es2019` entry point, and exported property, if you require a specific version.
